In her feature-length documentary, Woodstock: Now & Then, which aired on VH1 and the History Channel in commemoration of the three-day festival's 40th anniversary, two-time Academy Award-winning director Barbara Kopple focused on the behind-the-scenes elements of the original event and its lingering cultural mark. The film blends never-before-seen film footage and images from Woodstock with new interviews with some of its major players, current performances by some of the musicians who performed there 40 years ago, as well as some younger musicians who reflect the festival's influence in today's music scene.

Tzouris recorded first-hand accounts from performers such as Graham Nash, Jorma Kaukonen, Country Joe McDonald and Richie Havens with a Sound Devices 702T using its internal compact flash (CF) card as well as an external CF in a FireWire reader. For one of the new performances featured in the film, Tzouris recorded Grace Potter and the Nocturnals at a Woodstock revival concert. He set up several room mics and utilizing all eight tracks on his Sound Devices 788T recorder. The feeds were mixed on a Sound Devices CL-8 Controller and distributed to the three video cameras in the venue. He was also recorded several young students from the Paul Green School of Rock Music.

"My wife and I worked on this project together. There were times when she was recording interviews with the 702T and I was handling musical performances with the 788T," says Tzouris. "We relied on Sound Devices for this project because their products stand up to the rigors of field recording. I'm a huge fan and have been for several years now. The fact that the equipment is made in the U.S. is an added bonus and was a perfect fit for a story centered on such an iconic American movement."
